It is known that the payment of the wagons of a railroad train is done mechanically by the Train yourself to be done. For this purpose, insulated rail sections, rail contacts, Wheel buttons or the like, which are actuated by the wheels of the train and with each passing Rade put a counter into action, which then automatically shows the number of axles passing by. Such

jo rail contacts or wheel buttons are z. B. also used in drainage systems to ensure that the to activate the corresponding series of magnetic switches.

It is already known to transmit any signs or signals on the route, by attaching an iron core between the two rails of a track arranges, with the air gap between the two poles of the iron core over the wheels and the axles of the train is bridged and at the same time the air gap bridging remains constant as long as the clear space between the wheels is consistently

as is constant.

The present invention uses the present concept of bridging an air gap with the help of the wheels, but the device essential becomes easier and cheaper.

This is done according to the present invention in that a U-shaped Magnet is used, which surrounds one of the two rails of the track and its Poles face the two parallel faces of the wheel. Here is the air gap not only independent of lateral fluctuations of the car and the wheels, but also from the clear space between the wheels. One has in similar Weise already tried to transmit signals to the line by using U-shaped Magnets attached to the vehicles, with an iron part arranged on the track protruding between the poles of the magnets. However, this device is much more expensive because one on each vehicle must attach such a U-shaped magnet, while in the device according to the invention, the wheels themselves the bridging take over the air gap and the magnets only need to be attached to the places where a signal sign appears the route is to be transmitted.

The forwarding of the characters or signals to be transmitted on the route takes place now by the fact that the horseshoe magnets are magnetically influenced by the iron mass of the wheels in any way, e.g. B. by arranged on them windings, with which relays o. The like. In connection, a display cause. Both electromagnets and permanent magnets can be used on the track Magnets come into use.

*) The patent seeker stated as the inventor:

Dr. Robert Pfeil in Berlin-Grunewald.

Examples of the subject matter of the invention are shown in the figures. In Fig. Ι and 2 is 1 the rail of a track, on which the wheel 2 of the vehicle is running. 3 is the impulse magnet located next to the rail, which is expediently so, as shown in Fig. 2, namely that he Surrounding the wheel on both sides. This has the advantage that that between the poles of the pulse magnet and the air gap on both sides of the wheel in the event of lateral fluctuations remains the same in the position of the wheel. If one of the air gaps becomes larger, it becomes larger other smaller. This achieves that on

• 5 the impulse magnet has the same effect in every position of the wheel.

Fig. 3 shows another embodiment in plan, using an ordinary pulse magnet is applied and at the same time an example is given for the influence between impulse magnet and relay. The pulse magnet 3 is arranged next to the rail, its magnetic flux in the position shown over the iron mass of the wheel 2 flows. On the magnet 3, an excitation winding 4 is arranged, which by a battery 5 is fed, and in series with the excitation winding a pulse winding 6, which is connected to the winding 7 of a relay. In the idle state, the Armature 8 of the relay through the excitation winding 7, the current through the pulse winding 6 received, kept in the dressed state. The flux of force generated in the magnet 3 is now guided over the iron mass of the passing wheel 2, a reduction occurs of the current flowing in the windings 6 and 7, the armature 8 of the relay drops out and is indicated by the holding winding 9

pulled, which receives power from the battery 5. The anchor closes the one above the detector 10 flowing current that starts a counter or the like. After driving past of the wheel outweighs the current in the winding 7, so that the armature 8 is attracted again will. Instead of the holding winding 9, a spiral spring can also be used in a known manner or the like. A further improvement can be achieved by clicking on the stretch of track where the pulse magnet is arranged, a piece of rail 11 made of non-magnetic Material, a nickel steel rail ο. Like., Provides, so that the spread of the impulse magnet is reduced via the rail.

Fig. 4 shows a device in which a permanent magnet 12 is on the track is arranged, which influences the relay winding 7 through the pulse winding 6, wherein A permanent magnet 14 can also be used on the relay 13. The armature 8 of the relay magnet is attracted and discharged when a pulse occurs in this case the capacitor 15 previously charged by the battery 5 Armature 8, the capacitor is recharged by the battery, with the detector io, which is in the circuit of the capacitor, comes into action. By switching on the capacitor causes the current surge acting on the detector for a longer time persists. -. ■

Fig. 5 shows another version with a capacitor, the battery current at Dropping of the anchor is interrupted. Here, the capacitor 15 is again attracted Anchor charged by the battery 5, the detector 10 also receives power from the Battery through armature 8 of the relay. When the anchor drops, the detector is de-energized, the capacitor is discharged and then charged again when the armature is tightened. Here, too, the effect exerted on the detector is slowed down.
